PROBLEM TO BE SOLVED: To reduce resistance in cutting needles off from sealed needles one by one by making the sealed needles comprising a plurality of needles placed in a strip by an adhesive layer formed on one of surfaces. SOLUTION: The sealed needles 1 comprise a plurality of needles 2 on a flat which are connected in a strip via a plurality of parallel adhesive layers 3 formed only on an upper surface and can be rolled in a roll. Hot melt is heat-fused and welded within a shoulder of the needle 2 to provide rail-like parallel adhesive layers 3, so that the adhesive layers 3 also serve as guides when feeding the needles. Thus operation of making a strip of sealed needles can be simplified, and resistance in cutting the needles off from the sealed needles one by one can be reduced.
